Anatomy

1. Which process involves the body's natural defense against inhaled dust and allergens?

Correct answer: C

Rationale: The correct answer is C: Ciliary action. Cilia are tiny hair-like structures lining the respiratory tract that help trap and remove inhaled dust and allergens. When these particles are trapped in the mucus produced by the cilia, the cilia beat in a coordinated fashion to move the mucus and its trapped particles out of the respiratory system, preventing them from reaching the lungs. Cellular respiration (A) is the process by which cells generate energy from nutrients, not a defense mechanism. Gas exchange (B) refers to the exchange of oxygen and carbon dioxide in the lungs, not a defense mechanism. Bronchoconstriction (D) is the narrowing of the airways, often in response to triggers like allergens, but it is not the body's natural defense mechanism against inhaled dust and allergens.

2. A birthday party hat has a cone-shaped top with a radius of 5cm and a height of 12cm. What is its volume?

Correct answer: C

Rationale: Use the formula for volume of a cone: (1/3) * π * (radius)^2 * height. Substitute the values: (1/3) * π * (5cm)^2 * 12cm ≈ 150 cu cm.

3. Which term describes a substance's ability to undergo a change that transforms it into a different substance?

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, transforming it into one or more different substances with new properties.

4. The bones of the skull are classified as what type of bone?

Correct answer: C

Rationale: The correct answer is C: Flat bone. The bones of the skull are classified as flat bones due to their thin, flattened shape. Flat bones provide protection to vital organs and have a broad surface for muscle attachment. Long bones, like the femur, are characterized by their elongated shape, while short bones, such as those in the wrist and ankle, are cube-shaped. Irregular bones have complex shapes and do not fit into the other bone categories. In this case, the flat bones of the skull best fit the classification.

5. One staff suggests that they review the pattern of nursing care that they are using, which is

Correct answer: B

Rationale: The correct answer is B: 'system used to deliver care.' When a staff member suggests reviewing the pattern of nursing care being used, they are referring to the overall system or method in place for delivering care to patients. This includes the processes, protocols, and techniques used to provide nursing care. It goes beyond just following a job description, manual of procedure, or rules. By evaluating and potentially revising the system used to deliver care, staff can ensure that best practices are in place to provide high-quality and effective care to patients.

6. Which type of waves are capable of interference and diffraction?

Correct answer: d

Rationale: Both longitudinal and transverse waves can exhibit interference and diffraction phenomena.
